GENERAL SAFETY PRECAUTIONS

English

183

Muffler

The muffler is designed to keep noise levels to a minimum
and to direct exhaust fumes away from the user. A muffler
fitted with a catalytic converter is also designed to reduce
harmful exhaust gases.

For mufflers it is very important that you follow the
instructions on checking, maintaining and servicing your
machine.

Never use a machine that has a faulty muffler.

Regularly check that the muffler is securely attached to
the machine.

If the muffler on your machine is fitted with a spark
arrestor mesh this must be cleaned regularly. A blocked
mesh will cause the engine to overheat and may lead to
serious damage.

Locking nut

A locking nut is used to secure some types of cutting
attachment.

When fitting, tighten the nut in the opposite direction to the
direction of rotation of the cutting attachment. To remove
it, undo the nut in the same direction as the cutting
attachment rotates. (CAUTION! The nut has a left-hand
thread.) Tighten the nut using the socket spanner.

The nylon lining inside the locking nut must not be so worn
that you can turn it by hand. The lining should offer a
resistance of at least 1.5 Nm. The nut should be replaced
after it has been put on approx. 10 times.

!

WARNING! Mufflers fitted with catalytic
converters get very hot during use and
remain so for some time after stopping.
This also applies at idle speed. Contact
can result in burns to the skin.
Remember the risk of fire!

!

WARNING! The inside of the muffler
contain chemicals that may be
carcinogenic. Avoid contact with these
elements in the event of a damaged
muffler.

!

WARNING! Bear in mind that: The
exhaust fumes from the engine are hot
and may contain sparks which can start
a fire. Never start the machine indoors or
near combustible material!
